Underwater dye-marker release mechanism

ABSTRACT

A quantity of concentrated marker dyestuff is sealed between two lip-to-lip plastic cups. The cups are held together in a round tubular sleeve by a strong pre-loaded spring in response to a remote trigger pulse, whereupon the cups fall apart and release the dye.

 3. In combination in an underwater deep submersible dye-marker: a sleeve having an open end, a container disposed within said sleeve comprising a plurality of separable and mating portions for holding a quantity of dyestuff therebetween, means within the sleeve for maintaining said separable container portions together in sealable engagement within the sleeve, a ram for ejecting said container from the sleeve to free said portions from the maintaining means, whereby said portions aRe free to separate in the water to release the dyestuff.
